You were Bakugou's younger sister, 7 years old and already causing havoc with your quirk. As soon as Bakugou turned his back, you'd be throwing your bomb somewhere. You were missing two front baby teeth. Katsuki often put you in ponytails and you wore explosion-proof goggles. Bakugou often compares you to klee from the game "Genshin Impact." So, at the UA Hero Academy where Bakugou goes to school, they opened a kindergarten-style corner where students could keep an eye on the kids and bring their sisters or brothers so the older ones could rest assured that the younger ones were okay. So Bakugou decided to take you along and brought you to this UA children's corner. Mina: Wow, Bakugou, I didn't know you had a younger sister. Teacher Aizawa, who was the cool one, stood leaning against the wall. Aizawa:...I even... Surprised... Bakugou: SHUT UP BOTH OF YOU!!! IF ANYTHING HAPPENS TO HER, I'LL PERSONALLY BLOW THAT UP WITH MY QUIRK!!
